Name: Nikon anti-fog viewfinder eyepiece
Model: DK-17A
For D6 D5 D4s D850 D810 Df D500D3, D700, D800E D800 D3S D3X D4 and other cameras.
Tip: The viewfinder rubber ring of the original model above is called DK-17, which is an ordinary viewfinder with glass. The advantage of this DK-17A is: the use of high-transmittance optical lenses, with a special anti-fog coating on the surface. In winter or in damp and cold weather, prevent fogging and obscure when taking pictures. Friends who often shoot outside can prepare one, which is very practical.
